Thom's Mini Review: A disappointing lens. Optically weak at 400mm in my experience, despite Sigma's good-looking MTF charts. Could be a bad sample, but I've heard from enough other people who were disappointed with this lens that I don't believe my experience was just a sample problem. The Nikkor 300mm f/4 with TC-14E was sharper, as was my older 80-400mm (non-AFS) in most of the overlapping range. The new Nikkor 80-400mm (AFS) beats this lens easily, but the new Nikkor is also significantly more expensive.
